Overview - This is a great minimalist pack that's easy to carry and hike with. I got it in 2004 and the pack has long since been discontinued.

Likes

Shape - The tall skinny shape keeps the load close to your back and does not get in the way while hiking or scrambling. This pack is very streamlined for those minimalist packers that like everything in the main compartment

Side zipper - There is a full length zipper on one side of the pack which allows access to the contents of the pack

Fabric and webbing straps - This is the most unique feature of the pack and I've only seen this feature on some winter packs. The fabric straps can be used to hold gear like a snowboard, tarp or extra layers. They can also be flipped and clipped to the side straps to carry skis. The webbing straps are also useful for strapping extra layers or flip-flops/sandals

Heavy duty backpanel and bottom material - This pack has an extremely thick backpanel making it very comfortable when carrying bulky loads. The bottom material is also very thick and has held up after years of abuse. With many packs trying to shed weight, you don't find many with this thick of pack bottom material

Dislikes

Lack of external pockets - The trade-off of a minimalist pack is the lack of external pockets. Later models of this pack, The Catalyst Pack, added hip belt pockets

Conclusion - This is my current travel/sport pack. The flaps and straps are useful for strapping gear including a Frisbee which makes up for the lack of exterior pockets. I've had this pack for over 10 years and I've taken it all over the world while climbing and traveling. The pack has taken a beating but is still in good shape.
